    Abstract: Aspects of the subject disclosure may include, for example, embodiments include obtaining video content, the video content comprises a plurality of frames, monitoring, by an image sensor, a facial feature of a user to determine a visual focus of the user in relation to the video content, and detecting from a group of frames of the plurality of frames at least a reduction in movements of objects in the group of frames. Further embodiments include determining, according to the monitoring and the detecting, a measure of attention of the user within a region of the group of frames, determining that the measure of attention of the user within the region of the group of frames satisfies a threshold, and embedding in at least a portion of subsequent frames of the plurality of frames a visual advertisement in the region via a communication device. Other embodiments are disclosed.

    Abstract: Aspects of the subject disclosure may include, for example, a method comprising sending a first list of formats associated with media content to a client device via a network, and receiving from the client device a selection of a format from a second list of formats filtered from the first list using filtering criteria. The second list includes formats compatible with the client device. The filtering criteria can be based on performance metrics of the network and on capabilities of the client device. During presentation of the content at the client device in the selected format, transmission of the content item can be dynamically altered in response to a message that the presentation be continued in a different format. Other embodiments are disclosed.

    Abstract: A processing system may request, from an edge server, a first video chunk for a first segment and a second video chunk for a second segment of a video program stored in a cache of the edge server, where the first and second video chunks that are requested are encoded at a testing bitrate comprising a second lowest available bitrate in accordance with an adaptive bitrate streaming protocol. The processing system may further receive the first and second video chunks from the edge server via a network link, determine a bandwidth of the network link based upon the testing bitrate, the durations of the first and second video chunks, and an elapsed time to receive the first and second video chunks, and request a third video chunk for a third segment of the video program encoded at a highest available bitrate below the bandwidth of the network link.

    Abstract: A processing system including at least one processor may request, from an edge server, a plurality of video chunks for a plurality of segments of a video program to fill a video buffer, where the plurality of video chunks is encoded at a startup bitrate comprising a second lowest available bitrate of a plurality of available bitrates in accordance with an adaptive bitrate streaming protocol. The processing system may further receive, from the edge server, the plurality of video chunks, write the plurality of video chunks to the video buffer, and play out the plurality of video chunks from the video buffer when an occupancy level of the video buffer exceeds a threshold. In addition, the processing system may select a next video chunk for a next segment of the video program after the plurality of segments in accordance with a mapping function.
